Narrated Ibn 'Abbas and 'Aisha:

Abu Bakr kissed (the forehead of) the Prophet when he was dead. 'Aisha added: We put medicine in one side of his mouth but he started waving us not to insert the medicine into his mouth. We said, "He dislikes the medicine as a patient usually does." But when he came to his senses he said, "Did I not forbid you to put medicine (by force) in the side of my mouth?" We said, "We thought it was just because a patient usually dislikes medicine." He said, "None of those who are in the house but will be forced to take medicine in the side of his mouth while I am watching, except Al-'Abbas, for he had not witnessed your deed."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي مُوسَى بْنُ أَبِي عَائِشَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، وَعَائِشَةَ، أَنَّ أَبَا بَكْرٍ ـ رضى الله عنه ـ قَبَّلَ النَّبِيَّ ﷺ وَهْوَ مَيِّتٌ. قَالَ وَقَالَتْ عَائِشَةُ لَدَدْنَاهُ فِي مَرَضِهِ، فَجَعَلَ يُشِيرُ إِلَيْنَا، أَنْ لاَ تَلُدُّونِي. فَقُلْنَا كَرَاهِيَةُ الْمَرِيضِ لِلدَّوَاءِ. فَلَمَّا أَفَاقَ قَالَ " أَلَمْ أَنْهَكُمْ أَنْ تَلُدُّونِي ". قُلْنَا كَرَاهِيَةَ الْمَرِيضِ لِلدَّوَاءِ. فَقَالَ " لاَ يَبْقَى فِي الْبَيْتِ أَحَدٌ إِلاَّ لُدَّ ـ وَأَنَا أَنْظُرُ ـ إِلاَّ الْعَبَّاسَ فَإِنَّهُ لَمْ يَشْهَدْكُمْ ".
